Designated Port: Indicates the port is the designated port in CIST. Master Port: Indicates the port provides the lowest root path cost from the region to the root bridge in CIST. In CIST, each region is regarded as a 'switch', and the master port is the root port of that 'switch'. Alternate Port: Indicates the port is a backup of a root or master port in CIST. Backup Port: Indicates the port is a backup of a designated port in CIST. Disabled: Indicates the port is not participating in the spanning tree in CIST. Displays the port status. Forwarding: The port receives and sends BPDUs, and forwards user data. Learning: The port receives and sends BPDUs, and drops the other packets. Blocking: The port only receives BPDUs and drops the other packets. Disconnected: The port is enabled with spanning tree function but not connected to any device. Displays the LAG the port belongs to. 3.1.2 Configuring the MSTP Region Configure the region name, revision level, VLAN-Instance mapping of the switch. The switches with the same region name, the same revision level and the same VLAN-Instance mapping are considered as in the same region. Besides, configure the priority of the switch, the priority and path cost of ports in the desired instance.
